SWEEPER;

' application med Maren 24, '1921.' serial No. 455,349.

To all whom t ma concern:-

Be it known t at we, ,fIHoMAs H. ELL

and JOHN G. ScHonNmBnR, citizens of the United States, residing at NewYork, in the county of New York and State of New York,

have invented certain new and-useful Improvements in Sweepers, of whichthe followingis a s ecification.

This inventlon relates to ioor and carpet 'l0 sweepers, and moreparticularly to an im` y character which will contain a centralremovable dust collector arranged between the sweeping brushes in amanner that will cause a more effective operation of the apparatus.

Other objects of the invention will appear upon consideration of thefollowing detail description and accompanying drawings,

Figure 1 .is a transverse section taken through the device showing ourimprovement applied to the sweeper. l 4

Figure 2 is a cross section taken approxi'- mately on the line 2-21ofFig. 1, p

Figure 3 is a detail perspective view ofthe dust collecting element. .i

l Referring to the drawing by numerals, the .housing '1 may be of anypreferred construction a d is provided on its top with a chamber 2 ithinwhich a motor may be mounted for connection to a fan shaft A3 which'hasmounted thereon a suction fan 4 operable in a horizontal positionwhereby the 'blades will tend to draw rthe dust and dirt upwardly intothe fan chamber 5 through an opening 6 in the lower wall of the fanchamber as shown to`advanta in Fig. 1. A s out or 5o nozzle 7 projectsom the fan cham er and may be connected in any convenient mannerv to abag or receptacle for receiving the dust and dirt.'

The bottom wall ofthe housing lis p ce vided with two longitudinalopenings 8 and above these openings horizontal shafts 9 are providedupon-which brush rollers 10 are arranged. The brush rollers 10 areprovided with the bristles 11 and each end of each4 shaft 9 is providedwith traction rollers 12 which are adapted to engage the floor so thatrotary motion will be imparted to the brush rollers when the tractionrollers are moved across the surface of the-door.-

Disposed centrally within the housing 1 and located between the brushesis a dust collector shown in detail in Fig. 3 and indicated at 13. Thisis a yremovable element which is mounted in the housing 1 and projectsfrom one end to the other'thereof and has its sidewalls curved asindicated at 14, whereby the curvature will conform to the path of thebristles 11 ofthe brush element when the brushes are in operation. Thetop of the dust collector is provided with a longitudinal channel orgroove 15 which serves as a receptacle for a quantity of the dust anddirt while the device is in operation. This receptacle 15 is locateddirectly below the opening 6 and below the fan in the fan chamber sothat the tendency of the fan yvill be to draw the dust upwardly throughthe opening 6 but will permit a quantity of dirt to collect inthelongitudinal channel 15.

In operation, the device will be moved across the surface'of the flooror carpet and the traction rollers will, by virtue 'of theii` rotarymovement, im art `rotaryimovement to the brush rollers w ereby thebristles will engage the surface of the floor to thorou hly sweep andclean the same. The dust wi l be deposited in the channel 15 of the dustcollector and thesuction fan will be operated Iby the motonto draw thedust and eject it through the nozzle 7 where it will be re- 95 ceived ina bag or receptacle as is well known in the art.

Minor changes may be made in the details of construction withoutdeparting from the s iritof the invention or the scope of the nc aimslhereunto appended.`

1. In sweeping apparatus of the class described, the combination of ahousing, spaced parallel brush rollers in said housing, a dustcollectorv removably mounted between the brush rollers having. itsopposite sides concaved, said dust collector having on its top alongitudinal channel to act as a dust receptacle, and a. suction fanarranged above the 11o dust 'collector `to withdraw the dust from saidreceptacle.

2. In a sweeping ap aratus of the character described, thecom inationofa housing, spaced parallel brush rollers in said housing, a chamberpositioned on said housing, an

electric motor in said chamber, said housing having a depression formedin the top thereof, a fan in said depression to be operated by saidelectric motor in said chamber, a dust collector removably mountedbetween the brush rollers, the side walls of said dust collector beingconcaved and having a longitudinal channel formed on its top surface forreceiving the dust, and said housing being 15 In testimony whereof, wehave affixed our 20 signatures in the resence of two witnesses.
